[0041] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0042] Reference Figure 1 and Fig. 9 Now, the welded pipe extrusion device with insulated pressure roller provided by the utility model is described.

[0043] Reference Figure 1 A welded pipe extrusion device with insulated pressure rollers comprises a machine base 1, an insulating mechanism installed on the machine base 1, and an extrusion roller installed on the insulating mechanism.

[0044] Compared with the prior art, the welded pipe extrusion device with insulated pressing roller provided by the utility model uses an insulating mechanism to isolate the extrusion roller from the machine base 1. When the welded pipe is extruded, the current on the welded pipe will not flow to the machine base 1 through the extrusion roller, thereby avoiding the invalid current on the machine base 1, reducing the invalid power, saving power resources, and avoiding power waste.

[0045] Optionally, the insulating mechanism comprises an upper insulating assembly 5 and a lower insulating assembly 6 mounted on the machine base 1 . The squeezing roller comprises an upper roller 9 mounted on the upper insulating assembly 5 and a side roller 2 mounted on the lower insulating assembly 6 .

[0046] Optionally, the roller-insulated welded pipe extrusion device provided in this embodiment further includes an upper mounting mechanism 7 mounted on the upper insulating component 5, and the upper roller 9 is mounted on the upper mounting mechanism 7. Two upper rollers 9 and two upper mounting mechanisms 7 are provided, and one upper roller 9 corresponds to one upper mounting mechanism 7. The two upper rollers 9 are symmetrically arranged about the vertical center line of the machine base 1.

[0047] Optional, see Figure 2 The upper insulating assembly 5 includes: a top bolt 51, an upper insulating member 52 and a bottom bolt 53. The upper insulating member 52 is mounted on the machine base 1 through the top bolt 51, and the upper mounting mechanism 7 is mounted on the upper insulating member 52 through the bottom bolt 53. The upper insulating member 52 isolates the machine base 1 from the upper mounting assembly of the upper roller 9 to prevent current from flowing to the machine base 1. The top bolt 51 and the bottom bolt 53 do not contact each other, and the two are staggered.

[0048] When the welded pipe is extruded, when the upper roller 9 contacts the welded pipe, the current on the welded pipe flows to the upper roller 9 and the upper mounting mechanism 7. The upper insulating member 52 isolates the upper mounting mechanism 7 from the machine base 1 to prevent invalid current from existing on the machine base 1.

[0049] Optionally, the roller-insulated welded pipe extrusion device provided in this embodiment further includes a lower mounting mechanism 8 mounted on the lower insulating assembly 6, and the side roller 2 is mounted on the lower mounting mechanism 8. Two side rollers 2 and two lower mounting mechanisms 8 are provided, and one side roller 2 corresponds to one lower mounting mechanism 8. The two side rollers 2 are symmetrically arranged about the vertical center line of the machine base 1.

[0050] Reference Figure 3 Optionally, a first rotating shaft 21 is provided on the side roller 2, and the first rotating shaft 21 is installed on the lower mounting mechanism 8, and the side roller 2 can rotate around the first rotating shaft 21. The lower insulating component 6 includes: a sealed bearing sleeved on the first rotating shaft 21 and an insulating seal 62 arranged between the sealed bearing and the side roller 2. The sealed bearing is arranged between the first rotating shaft 21 and the side roller 2, and the insulating seal 62 seals the gap between the sealed bearing and the side roller 2. The insulating bearing 61 and the insulating seal 62 isolate the first rotating shaft 21 from the side roller 2. An insulating layer is plated on the side of the first rotating shaft 21. When the side roller 2 extrude the welded pipe, the insulating bearing 61, the insulating seal 62 and the externally plated insulating layer can prevent the current on the welded pipe from flowing to the machine base 1 through the lower mounting mechanism 8, further reducing the invalid current, reducing the invalid power of the current, and saving power resources.

[0051] Reference Figure 4 Optionally, the angle adjustment mechanism 3 includes: a mounting frame 301 connected to the spacing adjustment mechanism 4, a rotating seat 302 rotatably connected to the mounting frame 301, and a first driving assembly connected to the mounting frame 301. The side roller 2 is connected to the rotating seat 302, a mounting shaft is provided on the side roller 2, a rotating hole is provided on the rotating seat 302, the mounting shaft is inserted in the rotating hole, and the side roller 2 and the mounting shaft rotate in the rotating hole. The first driving assembly is used to drive the rotating seat 302 to rotate. When the rotating seat 302 rotates, it carries the side roller 2 to rotate together, thereby adjusting the inclination angle of the side roller 2.

[0052] Optionally, a mounting hole is provided on the mounting frame 301, and a second rotating shaft 303 is provided on the rotating seat 302. The second rotating shaft 303 is inserted into the mounting hole, and the second rotating shaft 303 is horizontal and vertically arranged with respect to the mounting axis. The first driving assembly is connected to the second rotating shaft 303, and the first driving assembly is used to drive the second rotating shaft 303 to rotate.

[0053] When the first driving assembly drives the second rotating shaft 303 to rotate, the second rotating shaft 303 drives the entire rotating seat 302 and the side roller 2 to rotate together, thereby adjusting the angle between the rotating axis of the side roller 2 and the horizontal plane. When the size of the welded pipe changes, the first driving assembly drives the second rotating shaft 303 and the rotating seat 302 to rotate, thereby adjusting the inclination angle of the side roller 2.

[0054] Reference Figure 5Optionally, the first driving assembly includes: a driving shaft 304 connected to the mounting frame 301, a driving gear 305 connected to the driving shaft 304, and a driven gear 306 connected to the second rotating shaft 303. The driving shaft 304 is arranged perpendicular to the second rotating shaft 303, one end of the driving shaft 304 is exposed outside the mounting frame 301, and the portion of the driving shaft 304 exposed to the mounting frame 301 is a polygonal column. The driving gear 305 is meshed with the driven gear 306.

[0055] When the size of the welded pipe changes, the staff rotates the drive shaft 304 with a wrench or other tool, and the drive shaft 304 drives the drive gear 305 to rotate. The drive gear 305 drives the driven gear 306 to rotate, the driven gear 306 drives the second rotating shaft 303 to rotate, and the second rotating shaft 303 drives the second rotating shaft 303 and the side roller 2 to rotate, thereby adjusting the inclination angle of the side roller 2 and expanding the contact area between the side roller 2 and the welded pipe.

[0056] Reference Figure 6 and 7 A modified implementation of the above-mentioned first driving assembly is: the first driving assembly includes: a rack 307 slidably connected to the mounting frame 301, a driven gear 306 connected to the second rotating shaft 303, and a driving member 308 connected to the mounting frame 301. The driving member 308 is connected to the rack 307, and the driving member 308 is used to drive the rack 307 to slide. When the driving member 308 drives the rack 307 to slide, the rack 307 drives the driven gear 306 to rotate, the driven gear 306 drives the second rotating shaft 303 to rotate, and the second rotating shaft 303 drives the second rotating shaft 303 and the side roller 2 to rotate, thereby adjusting the inclination angle of the side roller 2 and expanding the contact area between the side roller 2 and the welded pipe. It should be noted that the driving member 308 can be a hydraulic cylinder or a cylinder or other components, as long as it can drive the rack 307 to slide.

[0057] Reference Figure 8 and 9 A modified implementation of the first driving assembly is as follows: the first driving assembly includes: a turbine 309 connected to the second rotating shaft 303 and a worm 310 connected to the mounting frame 301. The worm 310 is arranged perpendicular to the second rotating shaft 303, one end of the worm 310 extends out of the mounting frame 301, and the portion of the worm 310 extending out of the mounting frame 301 is a polygonal column. The worm 310 is meshed with the turbine 309.

[0058] When the inclination angle of the side roller 2 needs to be adjusted, the staff rotates the part of the worm 310 exposed at the mounting portion with the help of a tool, thereby rotating the entire worm 310. The worm 310 drives the turbine 309 to rotate, the turbine 309 drives the second rotating shaft 303 to rotate, and the second rotating shaft 303 drives the rotating seat 302 and the side roller 2 to rotate together, thereby adjusting the inclination angle of the side roller 2.

[0059] It should be noted that the structure of the first driving assembly is illustrative rather than restrictive, and those skilled in the art may use other structures to drive the second rotating shaft 303 to rotate, such as Figure 2 A motor is added to the structure, the motor is installed on the mounting frame 301, the drive shaft 304 is connected with the power output shaft of the motor, and the drive shaft 304 is driven by the motor to rotate, which can further simplify the operation of the staff and reduce the labor intensity of the staff.

[0060] Optionally, the spacing adjustment mechanism 4 includes: a second driving assembly connected to the base 1 and a sliding support slidably connected to the base 1. Two sliding supports are provided, and two mounting frames 301 are respectively installed on the two sliding supports. The second driving assembly is used to drive the two sliding supports to move closer or farther at the same time.

[0061] A guide rail is provided on the machine base 1, and a slide groove is provided on the two sliding supports. The sliding supports are slidably installed on the machine base 1 through the cooperation of the slide groove and the slide rail. The second drive assembly includes a motor and a lead screw connected to the machine base 1. The lead screw is provided with two sections of threads in opposite directions. The two sliding supports are installed on the lead screw and cooperate with the lead screw threads. When the motor drives the lead screw to rotate, the lead screw drives the two sliding supports to move closer or farther away through the two sections of threads in opposite directions. It should be noted that the structure of the second drive assembly is only illustrative and not restrictive. Those skilled in the art may adopt other structures. For example, the second drive assembly includes two hydraulic cylinders, and the two hydraulic cylinders respectively drive the two sliding supports to move closer or farther away.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
